What’s up with the Furry Golf Microphones

I know that I’ve seen these furry microphones used at golf tournaments before, but why do they use it? I love the disgust in Tiger’s face knowing that he has to talk into what looks like untrimmed genital. I can only guess these types of mics have something to do with the wind or sound, but if it makes better sound why wouldn’t they use it at other outdoor events. Plus, I can only imagine the germs that get caught up in that thing.

Any explanation of this would be greatly appreciated!
